I don't really agree, I think most studios recognize the importance of music in games, and I know for a fact the composers take it seriously (just check out GANG those guys aren't messing around). I know quite a few game composers myself and can attest to how serious they take their job and the impact it has on players.
For recent games with soundtracks that were very vital check out Uncharted 2, Modern Warfare 2 and Brutal Legend. All of these used the soundtrack to drive home emotional parts of the game.
